Jessica Simpson Welcomes Second Child

The fashion mogul, 32, and her fiance, Eric Johnson, 33, have welcomed their second child into the world, a rep for the star told ABC News today.

In December, Simpson confirmed pregnancy rumors by tweeting a photo of her daughter, Maxwell, above the words, "BIG SIS." The two children will be very close in age: Simpson gave birth to Maxwell just last May.

"The crazy thing is, I never knew a wiener could actually make me nauseous," she said. "Well I guess I just told the world that I'm having a boy!"

A month later, Simpson feted her little boy with a sweet Tom Sawyer-themed baby shower, complete with down-home decor, a Southern-style menu, and one very important request from the mommy-to-be: Thousand Island dressing at the salad bar!
